This invention relates genial-ally" to cameras of the portable type suchas are employed for taking isolated exposures, and the present case is arefiling of my abandoned application, Serial No. 402,952, filed October28,1929.

It is a general ob]ect of the present invention to devise a novelstructure which. will preclude the possibility of an operator taking adouble exposure.

. pear from the which I have set forth the preferred embodie It isafurther ob]ect of this inventionto devise novel mechanism cooperatingwith the operating lever of a camera :shutter mechanism, which willautomatically preclude improper operation of the shutter without,however, interfering with the nor mal shutter operations.

a It is a further object of this invention to devise a novel form ofguard for the operating lever of the camera shutter, together with novelmeans for its automatic op: eration. Q 7 Further objects of theinvention will ap following description in ment of my invention. It isto be under: stood'that the appended claims are to be accorded a rangeof equivalents consistent with the state of the prior art.

April 17,1929, now Patent No.1,87 6, 143, issued April 13, 1932, and No. 361,108, filed May 7, 1929,now Patent No. 1,850,460, issued March 22, 1932, I have disclosedmechanism for use in conjunction with portable cameras, which precludesthe taking ofdouble exposures. The specific meansdisclosed in thoseapplications consists oflatch or looking means, engaging a movable partof the shutter mechanism in such a manner as to-lock the shutteraftereach operation thereof. This lock is then automatically disengagedwhen the operator moves an unexposed film portion in place of theexposed portion. In the pres} ent instance, I havedisclosed a structurewliichwill also preclude" the taking of double exposures, but in placeof means looking with a movable member of the shutter mechanism, I haveshown a guard or equivalent member which is automaticallymoved toaposition to overlie or protectthe shutter operating lever, thuspreventing its improper operation. 7 1 Referring to thedrawings for adetailed description of the-present invention, I have shown in Fig. 1 acamera consisting of the body portion 10, shutter mechanism 11, and'acollapsible bellows 12 connectingthe shutter mechanism with the bodyportion 10. As is customary with cameras of this type, the body portion10 is constructed so as to house a'. photographic, film, and means isprovided which can'be manually operated so that after exposure of-acertain film portion, an unex posed portion can be moved into place to.be exposed. This film changing means is pref-' erably formed by arotatable shaft 13, which is adapted to detachably engage one end of aroller 14. Shaft 13 is provided witha ring 16 or equivalent meanswhereby the shaft 13 and roller 14 can be rotated manually when desired.The unexposed film rollis of course carried in the other end of bodyportion 10, and as the film is exposed, it is wound up upon roller 14.

Shutter mechanisms for use with portable cameras are provided withmanual means to effect a desired shutter operation, as for example asnapshot or a time exposure. In

some instances the mechanism is operated by a single manually movablelever while in other cases the shutter is conditioned or tensioned byone lever and is released by another operating member. In the drawingsthe particular shutter mechanism illustrated is equipped with one leverwhich is depressed from an initial position to condition or tension theshutter mechanism, and another member is provided which is manuallydepressed for releasing the shutter. Upon releasing the shutter, theconditioning lever returns to initial position. The conditioning leveris indicated at 17 and is supported upon the housing of the shutter,mechanism 11. In Figs. 1 and 2,lever 17 isshown in'initial position. Inoperating the shutter, the lever is depressed to the position shown inFig. 5 to tension or set the shutter mechanism. Member 18 is thendepressed, as indicated by the dotted lines in Fig. 5, to release theshutter, and during the shutter operation, lever 17 returns to initialposition. In taking a time exposure, lever 17 generally returns onlypart way back to its initial position when member 18 is first depressed,but upon depressing this member a second time, lever 17 returns toinitial position. The outer end portion 19 of lever 17 is the part whichis generally engaged by the thumb or finger of the operator.

In my invention I provide means in the form of a hood 21, adapted in oneposition to overlie portion 19 and thus preclude its normal engagementby an operator. This hood 21 can be formed of a piece of sheet metalbent means of pin or shaft 22.

or curved in the manner shown in Figs. 5 and 6. To permit movement ofhood 21 between its operative or active position, and its out of the wayor inactive position, one end of the hood is preferably pivotallymounted by (Fig. 5.) For biasing the hood in one direction, a smallhelical spring 23 has been shown about shaft 22, and this spring isarranged to normally tend to. rotate hood 21 as shown inFig. 4, in whichposition it permits free access toportion 19 of lever 17. Its activeposition is shown in Figs. 2 and 3, in which it is swung forwardly tooverlie portion 19, so that when lever 17 is in its normal or initialposition, hood 21 precludes the operator from engaging lever portion 17A v pivotally mo To effect automatic operation of hood 21,

I preferably provide means which will cause this hood to move to itsactive position responsive to movement of lever 17, as for exampleresponsive to movement of this lever from its initial to its depressedposition, and means is also provided for effecting automatic return ofthe hood to its inactive position when the operator moves an unexposedfilm portion in place of an exposed portion. As a suitable and desirableembodiment of means for effecting automatic movement of the hood to .itsactivegiosition, I provide a 'lever 26,

d as by means of pin 27. It may benote tthis time that pivot pin 27, andalsop i tal shaft 22, can be carried by portions of a small metalbracket 28, this bracket being in turn connected to the plate 29 ofshutter mechanismll, as by means of rivets or screws 31. Lever 26 isprovided with a curved finger 32, and this finger is arranged to engagethe back face of hood 21. Movement of lever 26 from the position shownin Fig. 4 to that shown in Fig. 3, serves to swing the hood forwardlyfrom inactive to its active position. To'efiect such movement of lever26-automatically responsive to movement of lever 17 this lever isprovided with a.

small arm 33. The end portion 34 of lever 26'is adapted-to extendintothe path of movement of arm 33, so that when lever 17 is moved from itsinitial to its depressed position, arm 33 engages portion 34, thusrotating lever 26 in a clockwise direction as viewed in Fig. 4, to swinghood 21 forwardly to its active position. When lever 17 is fullydepressed, portion 34 occupies the position immediately behind arm 33,thus effectively locking lever 26 and hood 21 in the position shown inFig. 6.

Inorder to effect automatic movement of hood 21 back to its inactiveposition, I have shown means actuated responsive to rotation of shaft13. This means preferably utilizes a flexible motion transmitting cable36, such as are commonly used on portable cameras for operating shuttermechanisms. One end of this cable is retained by a clamp or bracket 37,secured to one side wall of the camera body portion 10. A pin 38projects from this end of cable 36, and is arranged in the path ofmovement'of a member 39, this member being rota-table together withshaft 13. When shaft 13 is rotated in a counterclockwise direction, asviewed in Fig. l as by engaging ring 16, pin 38 is repeatedly forcedinto cable 36, although since it escapes by member 39, it does notprevent rotation of shaft 13, to wind up the exposed film portion. Theother end portion 41 of cable 36 extends forwardly to the shuttermechanism 11, and is shown mounted upon bracket 28. An actuating pin 42extends from this end of the cable, and'this pin is projected outwardlyeach time the'pin 38 is forced inwardly by engagement with Ill;

member 39. Biasing means is of course inherent with cable 36, so thatpin 42 is normally biased toward retracted position,and so that pin 38is normally biased toward projected position.

T 0 cooperate between'actuating pin 42 and lever 26,I provide anotherlever 43, this lever beingpivotally' connected to bracket 28 by means ofpin 44. One end of this lever is formed to provide a curved finger 46,this finger extending loosely through an aperture 47 in lever 26. Theother end portion 48 of lever43, extends in the path of movement ofactuating pin 42. In order to frictionally retain lever 43 in a shiftedposition after it has been actuated by pin 42, a small struck up portion51 has been provided immediately below portion 48. It is apparent thatbecause of the engagement of curved finger 46 with lever 26, levers 43and 26 are constrained to rock in unison, but in opposite directions. Itmay be also noted that the pivotal axes provided by pins 27 and 44, aresubstantially normal to the pivotal axis afforded by pivotal shaft 22for hood 21. In order to protect certain of the working parts, a smallhood 52 can be provided, as shown in Fig. 1, this hood having a portionthereof cut away as indicated at 53 to permit free movement of guard 21.

In Fig. 9, suitable means is shown for properly guiding the motiontransmitting cable 36, whereby this cable is properly folded within thecamera when the camera is collapsed. Thus, I have shown links 56 and 57pivotally connected to the shutter support and to the side wall of bodyportion 10 respectively, these links being associated by a pin and slotconnection 58. An intermediate portion of the cable 36 is attached tolinks 56 and 57 at the point of connection 58 so that the cable isdoubled downwardly when the camera is collapsed.

The operation of my device can be explained as follows. It will bepresumed that an unexposed film portion is in proper position within thecamera, and that hood 21 is in inactive position as shown in Fig. 4.Suitable lettering such as O. K. can be placed upon the face of the hoodnow exposed to indicate that an exposure can be made. If the operatornow desires to take an exposure, he depresses lever 17 to set theshutter mechanism. During movement of lever 17 arm 33 engages portion 34of lever 26, and thus rotates lever 26 in a clockwise direction to theposition shown in Fig. 6. Rotation of lever 26 causes finger 32 to swinghood 21 outwardly, and also lever 43 is rotated in a counterclockwisedirection. lVhile lever 17 remains in depressed position, lever 26 islooked, as shown in Fig. 6. The operator then depresses member 18 toeffect an exposure, and lever 17 returns to its initial position.Portion 19 of lever 17 then underlies hood 21, as shown in Figs. 2 and3, thus preventing or precluding its engagement by the finger of anoperator. While the parts are thus positioned, it is impossible for theoperator to effect a second exposure, upon t e same film portion,without first rotating shaft 13. Suitable lettering such as N. G. uponthe side of the hood now exposed, provides a visual warning so that theoperator will not attempt another exposure until the film has beenchanged. I

Upon rotation of shaft 13 to wind up the exposed film portion, movementof pin 38 causes actuating pin 42 to be projected, to.

rotate lever 43 in a clockwise direction. Lever 26 correspondinglyrotates in'a counterclockwise direction, to permit hood 21 to withdrawunder tension of spring 23. Lever 43 is of course retained in. oneoritheother of its operating positions, by :the friction occasioned by thedetent or projection 51. After hood 21 has withdrawn in its inactiveposition, lever 17 can be again operated to effect another exposure. Itwill be noted that lever 17 is not obstructed in an way in its movementfrom depressed bac to initial position. This is a desirablecharacteristic of the present invention, as it permits accurate timingof the shutter operation; 1

It is apparent that the details of the device described above aresusceptible of-modifica tion and simplification. For'example undercertain conditions, I have found that the hood may be formed as a partoflever 26 by providinga suitable widened portion 35 on finger .32, asshownv in Figs. 10 and 11. Other. modifications may suggest themselveswithin the scope'of the invention, as deter I mined by the state of theprior art.
